Altitude & Atmosphere Testing

Dual Altitude Chamber System with independent control for each chamber.

Abbess Altitude and Atmosphere Testing Chambers are produced with an emphasis on careful coordination of the pumping equipment, the chamber properties and component and controls. Abbess has a highly evolved set of systems and tools specifically designed for recreating Altitude and Atmosphere conditions, Flight & Altitude Simulation, Low Earth Orbit (for experimentation and/or satellite testing), and Deep Space Test environments.

Like all systems designed and manufactured by Abbess Instruments, these systems can be custom engineered and produced to meet your specifications.

Thermal and Vacuum Chamber functionalities combine with profiling proportional control to give operators the tools they need to ramp both temperature and pressure and even customize gas mixtures for highly parallel chamber environments. Abbess Control Systems can be configured for basic function or customized for sophisticated and integrated tests, with customer specific PC/Touchscreen GUI and robust data-logging functionality.

Abbess Altitude & Atmosphere Testing Chambers are ideal for simulating the effects of high altitudes for satellites of all sizes, products, and packaging.

This vacuum chamber system is configured as a versatile platform to conduct aeronautic component tests with. With a temperature range of +200C to -96C, this system is ideal for robust test procedures in both industrial and academic laboratories.

Satellite Testing Vacuum Systems engineered and built for the satellite industry. These systems can be customized for your desired test procedure. The inner Thermal Shroud can be coated with AeroGlaze® to further improve your testing environment.

This Vacuum System allows items placed inside to be exposed to specific vacuum levels and rates of change. A Vacuum Cycle Controller (VCC) is used to automate control functions. The VCC enables system monitoring and control via touch screen buttons and graphic indications of sensor data registered and controlled by a PC with a user-specific Graphical User Interface (GUI).

The tall size of the altitude chamber allows sample carts to be wheeled in with ease. By being able to load the chamber efficiently, it is easier to subject the product sample process to various altitudes. The operable clear acrylic port provides quick and easy access to a test system without needing to unclamp the larger door.

Abbess Instruments has carefully designed three-levels of Altitude Chamber vacuum systems of varying complexity. Listed are standard packages with can be bought as a bundle, or can be customized to fit certain specifications.

The Abbess Thermal Vacuum Chamber System shown allows Article(s) Under Test placed inside to be exposed to high vacuum (10e-8 range) as well as heated and cooled via conductive contact with the Gold Plated Copper Thermal Plate.

Performance Specifications

All performance specifications stated, including but not limited to, pump-down rates and vacuum levels make the following assumptions:

The Vacuum Chamber is empty.

The Vacuum Chamber and other system components are clean and dry.

The System is being operated at Sea Level

The ambient temperature is 18°C +/- 2°C

All system components, including those not supplied by Abbess, are appropriate for the system and are functioning properly.

The specifications are not impacted by the properties of your product.

If you require performance specifications for conditions other than those listed above, it is vital that you make this known to Abbess Instruments in writing. Generally Abbess Instruments recommends choosing chamber and pumping system qualities capable of achieving a theoretical vacuum at least an order of magnitude better than the desired operational vacuum.

It is to be noted that a specification described as '10-5 Torr' is a range, and means the clean, empty, dry chamber system is capable of reaching some undetermined value between 1.0x10-5 and 9.9x10-5 Torr: The (clean, empty, dry) chamber is deemed compliant whether its As-Built base vacuum is 1.0x10-5 Torr or 9.9x10-5 Torr. It does not mean that the chamber is guaranteed to reach every level within that range.
